Cameron Diaz thinks antiperspirant is the pits: "I don't believe in antiperspirant," she told E! Online's Marc Malkin at the premiere of The Other Woman last week. "It's really bad for you. I haven't used it for almost 20 years."

Whoa: bravery. She went on: "You're stinky because you use antiperspirant," said Cameron. "It keeps all the stink in."

Just to make sure we're all on the same page: Technically speaking, antiperspirants and deodorants are two different things—though many of the products people swipe on are labeled as both. Just as their names imply, antiperspirants combat sweating, and deodorants fight bad smells.

And while we're not sure exactly what Cameron is referring to when she says that antiperspirant is bad for you, it's worth pointing out that, according to the American Cancer Society, there's currently no clear link between underarm antiperspirants and a person's breast cancer risk, as some people believe.
